Description

  The present invention relates to a mask that covers a nose, a mouth, and the like of a wearer's face.

Masks used in daily life, such as when illnesses, pollen, yellow sand, and other dusts, block the gap between the mask and both sides of the nasal bridge in order to enhance the effect of blocking foreign matter. Yes.
However, as the airtightness increases, the breathability for breathing decreases, so the ratio of mouth breathing increases, and the breath containing high moisture accumulates inside the mask, and the breath containing high moisture leaks from the mask. Will be put out. As a result, when glasses or goggles are worn with the mask, the glasses or goggles are clouded by moisture, which may obstruct the field of view.
Therefore, in the conventional mask, a flexible sheet piece having an adhesive layer that adheres to the epidermis of the nose is fixed to the inner surface side of the mask body covering the mouth, and the restoring force of the flexible sheet piece allows the By pulling the epidermis outward, the nasal cavity was widened to facilitate nasal breathing (see, for example, Patent Document 1). As a result, the frequency of mouth breathing is reduced, and fogging of glasses and the like due to moisture of exhalation is reduced.

However, since the flexible sheet is attached to the inner surface of the mask main body, the flexible sheet is in direct contact with the mask wearer's skin through the adhesive. It was. Since it is essential that the flexible sheet has flexibility, an elastic body made of a hard material such as plastic or metal is used as the forming material. When a flexible sheet made of such a hard material directly touches the mask wearer's skin, there is a feeling of foreign matter, and the wearer may feel pain.
Moreover, since the expansion and contraction of the flexible sheet can hardly be expected, when a flexible sheet made of a hard material is directly attached to the skin, it cannot follow the movement of facial muscles such as changes in facial expression, There was a risk of feeling uncomfortable because the skin was pulled.

  An object of the present invention is to provide a mask that can perform nasal breathing well and has a good wearing feeling.

The invention described in claim 1

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

[First embodiment]
FIG. 1 is a perspective view showing a mask 100 according to a first embodiment of the invention to which the present invention is applied. Moreover, FIG. 2 is the front view which looked at the mask 100 of the wearing condition from the front.
In the following description, the face side is the rear side, and the opposite side is the front side. Further, the upper side in the state where the mask 100 is worn is the upper part, the lower side is the lower part, the left hand side of the wearer is the left, and the right hand side is the right.

  The mask 100 is, for example, a disposable pleated mask 100. Specifically, as shown in FIGS. 1 and 2, the mask main body covers the nose, mouth, chin (target part) and the like of the wearer's face. Part 1, a pair of left and right ear hooks 2, 2 for locking the mask body 1 to the wearer's ear, and the upper edge of the mask body 1, and the nasal cavity of the wearer of the mask 100 A nasal cavity expanding portion 3 is provided.

  The mask main body 1 is formed, for example, in a substantially rectangular shape when viewed from the front, and a plurality of pleats 11 that can spread in the vertical direction are formed in the vertical direction. When the mask 100 is worn, the pleats 11 spread in the vertical direction so that the mask main body 1 bulges outward so that the nose, mouth, chin, etc. of the wearer's face are formed. It is supposed to be covered.

The mask main body 1 is formed of a sheet material, and the sheet material is formed of a single fabric or a plurality of superposed fabrics such as a spunbond nonwoven fabric, a melt blown nonwoven fabric, a spunlace nonwoven fabric, a gauze, a towel cloth, and the like. ing.
The manufacturing method of the mask body 1 may be any known method, and detailed description thereof is omitted.

A pair of left and right ear hooks 2 and 2 are provided on both edges 12 in the left and right direction of the mask main body 1.
Each of the pair of left and right ear hooks 2 and 2 may be, for example, a flat string, and a rubber string may be sewn and the whole may have elasticity.
One end of the left ear hook 2 is sewn to the upper end of the left edge of the mask body 1 and the other end is fixed to the lower edge of the left edge of the mask body 1 by bonding or welding.
Also, one end of the right ear hook 2 is sewn to the upper end of the right edge of the mask body 1 and the other end is fixed to the lower edge of the right edge of the mask body 1 by bonding or welding. .

[Nasal cavity extension]
FIG. 2 is a side view of the nasal cavity expanding portion 3 provided on the upper portion of the mask main body 1 in a state where the pleats 11 are not unfolded, and FIG. 3 is a plan view.
The nasal cavity expanding portion 3 includes a long flat elastic member 31 fixed to the upper edge portion of the outer side surface of the mask main body portion 1 and a sticking portion 32 fixed to the upper edge portion of the inner side surface of the mask main body portion 1. And a release paper 33 that covers the adhesive side of the sticker 32 on the wearer side.

The elastic member 31 is provided in the center part along the left-right direction in the upper edge part of the outer side surface of the rectangular mask main-body part 1 as shown in FIGS. It arrange | positions so that it may overlap with the position which is a little above the nose wings of the right and left of the nose. The elastic member 31 is intended to expand the nasal cavity using a restoring force (elastic force) from a bent state.
Therefore, the elastic member 31 is made of a synthetic resin such as PP (polypropylene), PE (polyethylene), PET (polyethylene terephthalate), or a synthetic resin having moderate elasticity such as silicon, or a rust-proof metal.

  The elastic member 31 has a surface facing the mask main body 1 fixed to the outer surface of the mask main body 1 by welding or bonding using heat or ultrasonic waves. The elastic member 31 may be attached by any method that can be fixed with sufficient strength that does not cause peeling due to the elastic force of the elastic member 31. Moreover, you may utilize the double-sided tape which has sufficient adhesive force.

The sticking part 32 has a strip shape, and as shown in FIGS. 2 and 3, the two sticking parts 32 are masked in a state along the left-right direction at the upper edge part of the inner side surface of the rectangular mask main body part 1. It is provided on both the left and right sides with the central portion of the main body 1 interposed therebetween.
These sticking portions 32 and 32 have the same width as the elastic member 31 and a length less than half of the elastic member 31, and the left and right end portions of the elastic member 31 sandwiching the mask main body 1. In contrast, they are provided at the same position.
These adhering portions 32, 32 are so-called double-sided tapes in which an adhesive is applied to both sides of the sheet, are adhering somewhat above both nostrils of the mask wearer's nose, and are elastic through the mask main body 1. The member 31 can be maintained in a bent state along the shape of the nose.

  The pressure-sensitive adhesive of each sticking part 32, 32 is a pressure-sensitive acrylic acid adhesive with low allergenicity and has a sufficiently small influence on the human body in consideration of the presence of odors and volatile components. Since it is pressure sensitive, it is difficult to cause curing due to a chemical reaction, etc., and it can be peeled from the epidermis of the nose with a larger pulling force than the elastic material of the elastic member 31 even after sticking while maintaining long-term adhesiveness. . Moreover, since it is an acrylic acid type | system | group, high adhesiveness can be maintained even in the epidermis to which sebum adhered.

  Although it has been described above that the mask main body 1 may be formed of a plurality of overlapping fabrics, the formation of the nasal cavity expanding portion 3 in the mask main body 1 is elastic if the overlapping fabrics are easily separated from each other. Since the tension based on the elasticity of the member 31 is difficult to be transmitted to the epidermis of the mask wearer's nose, it is desirable to make the cloths partially partially or to make the overlapping cloths difficult to separate by bonding or welding.

In addition, although the sticking part 32 should attach said adhesive to the wearer's nose side surface, even if the mask body part 1 side surface is not an adhesive and uses the adhesive material which cannot peel. good. That is, since the sticking part 32 does not need to be peeled off once attached to the mask main body part 1, it may be fixed by adhesion or may be welded by heat or ultrasonic waves.
Moreover, the sticking part 32 may be the layer of the said adhesive formed on the inner surface of the mask main-body part 1 by the same shape and the same arrangement | positioning as a tape instead of a double-sided tape.
Moreover, since the sticking part 32 should just be able to transmit the tension | tensile_strength based on the elastic force of the elastic member 31 to the epidermis of a nose, it has a somewhat larger adhesive surface including the whole plane of the left end part or right end part of the elastic member 31. It is good also as a structure.
Further, only one sticking portion 32 having the same size as the elastic member 31 or an adhesive surface somewhat larger than the entire plane of the elastic member 31 may be used.

  As shown in FIG. 2 and FIG. 3, the release paper 33, in which a layer of wax or wax is formed on the surface of the sticking part 32, respectively, on the nose side of the wearer 32, 32. 33 is stuck and the sticking surface of each sticking part 32 and 32 is coat | covered. Each release paper 33, 33 has the same shape and the same size as the attachment surfaces of the attachment portions 32, 32. When the mask 100 is worn, each release paper 33, 33 is attached to each attachment portion 32, 33. It peels from 32 and is discarded.

[How to wear a mask]
FIG. 4 is a plan view showing a state of the nasal cavity expansion portion 3 while the mask 100 is worn.
As shown in FIGS. 2 and 3, the mask 100 peels the release papers 33 and 33 of the nasal cavity expansion part 3 from the sticking parts 32 and 32, respectively.
And the formation position of the nasal cavity expansion part 3 of the mask main body part 1 is set to the upper side, the surface on the elastic member 31 side is directed to the outside, and the surface on the sticking part 32 side is directed to the wearer's face side. Hook 2 and 2 respectively on the left and right ears. After the left and right ear hooks 2 and 2 are hooked, each pleat 11 of the mask main body 1 is pulled up and down to deform the mask main body 1 into a three-dimensional shape that protrudes forward.

As a result, the sticking surfaces of the sticking parts 32 and 32 that are exposed are stuck to the epidermis at positions slightly above the right and left nose wings of the wearer's nose. As a result, as shown in FIG. 4, the elastic member 31 is held in a state in which both right and left end portions are bent rearward across the nose bridge and elastically deformed following the shape of the nose.
At this time, the elastic member 31 generates an elastic force to return to the original flat plate shape, and applies tension to the outer front of the left and right skins of the nose bridge. As a result, the outer wall of the nasal cavity is pulled forward to expand the cross-sectional area of the nasal cavity.

  Further, the used mask 100 can be removed by removing the ear hooks 2 and 2 from the ears and peeling the sticking parts 32 and 32 from the epidermis of the nose.

[Technical effects of the embodiment]
The mask 100 includes a mask main body 1 that covers a target portion of the wearer's face, a pair of left and right ear hooks 2 and 2 for locking the mask main body 1 to the wearer's ears, And a nasal cavity expanding portion 3 for expanding the nasal cavity.
Therefore, the wearer of the mask 100 can easily perform nasal breathing even when the nasal cavity is widened by the nasal cavity expanding portion 3 and the mouth and nose are covered by the mask main body portion 1, and the mouth breathing ratio can be increased. Can be reduced. As a result, the moisture content of the exhaled breath leaking from the mask main body 1 can be reduced, and the occurrence of cloudiness due to moisture can be reduced even when wearing glasses or goggles.

Further, the mask 100 has a flat elastic member 31 and a sticking portion 32 for sticking the elastic member 31 to both sides of the wearer's nasal bridge via a sheet material forming the mask main body 1. 32.
For this reason, since the elastic member 31 made of metal, resin, or the like applies tension to the epidermis of the mask wearer's nose through the sheet material, the feeling of foreign matter such as when the elastic member 31 is in direct contact is reduced and soft. The nasal cavity expansion state can be maintained with a simple touch. Therefore, it is possible to improve the feeling of wearing the mask.
Moreover, since the upper edge part of the mask main-body part 1 can be closely_contact | adhered to a mask wearer by the sticking parts 32 and 32, it is possible to fully ensure the blocking | blocking performance of a foreign material, performing breathing easily.
Furthermore, since the elastic member 31 is stuck through the sheet material, the movement of the facial muscles is not restricted, and the occurrence of discomfort and the like can be sufficiently reduced.

Moreover, in the mask 100, since the nasal cavity expansion part 3 is provided in the upper edge part of the mask main-body part 1, when wearing it, the sticking parts 32 and 32 are located above both nose wings of a nose, without being aware of alignment. And can be easily worn.
Also, with the above arrangement, the nasal cavity expanding portion 3 can be disposed in the vicinity of the wearer's nose when wearing the mask, and the nasal cavity can be expanded more effectively.

  Moreover, since the said nasal cavity expansion part 3 has the release paper 33 and 33 which coat | covers the sticking surface of the sticking parts 32 and 32, it protects the sticking surface of each sticking part 32 and 32 from dust and dirt. Until the mask 100 is used, it becomes possible to maintain the adhesiveness of each of the sticking portions 32 and 32 high.

[Second Embodiment]
The other example of the elastic member of the nasal cavity expansion part 3 is shown as 2nd embodiment. In addition, about the mask or nasal cavity expansion part demonstrated after this 2nd embodiment, all the points different from the mask of FIG. 1 shall be demonstrated exclusively, and description is abbreviate | omitted about the same structure as the mask of FIG.

Although the elastic member 31 described above has a strip shape, the invention is not limited to this, and any member having a width about the right and left nose wings of the nose in the left-right direction may be used. In that case, it is desirable that the elastic member has a symmetrical shape on the left and right.
An example is shown in FIG. For example, a planar shape may be a waveform like an elastic member 31A shown in FIG.
Further, like the elastic member 31B shown in FIG. 5B, the planar shape may be a circle, more preferably an oval.
Moreover, it is good also as strip shape like the elastic member 31C shown in FIG.5 (C), and the both ends which are rounded. In the case of an elastic member that is not a strip, roundness may be formed at both ends.

[Third embodiment]
Another example of the nasal cavity expanding member is shown as a third embodiment. FIG. 6 shows a nasal cavity expansion portion 3D having soft members 34D and 34D having flexibility on the wearer side of the elastic member 31.
As the soft member 34D, for example, a silicon resin can be used. For example, another material having flexibility enough to be depressed by pressing with a hand may be used.

Each flexible member 34D, 34D is inserted between each sticking part 32, 32 and the mask main body part 1, and is formed in a size that can be in close contact with the entire plane of the sticking part 32.
The soft member 34 </ b> D may be interposed between the elastic body 31 and the sticking portion 32, and may be interposed between the mask main body 1 and the elastic member 31. In that case, the number of the flexible members may be one, and the flexible member is formed in a size that can be in close contact with the entire plane of the elastic member 31.

  As described above, by providing the flexible members 34D and 34D in the nasal cavity expanding portion 3D, it is possible to further reduce the sensation of the foreign body due to the elastic member 31, and to maintain the expanded nasal cavity state with a soft feel, and to improve the feeling of wearing the mask. It becomes possible to make it better.

[Fourth embodiment]
Another example of the mask is shown as the fourth embodiment. FIG. 7 illustrates a mask in which a cooling agent having a cooling effect is disposed on the nasal cavity expansion portion 3E.
It is known that nasal congestion caused by vasodilation due to an allergic inflammatory reaction is improved by constricting blood vessels. Therefore, it is possible to give the mask a cooling effect by the cooling agent, to improve the nasal congestion of the mask wearer, and to perform nasal breathing well.
As the cooling sensation agent, there are a single component having a cooling sensation effect and a one having a cooling sensation effect by reaction with moisture. The former includes menthol, salicylic acid, camphor, mint oil, and the like, and the latter includes ammonium nitrate, urea, or a mixture thereof.

Some of the above-mentioned cooling sensation agents may have some effects such as irritation on the skin, so it is desirable to arrange them so that they do not touch the skin directly. For example, as shown in FIG. 7, a cooling sensation sheet 35 E containing a cooling sensation agent having the same size as that of the elastic member 31 may be interposed between the elastic member 31 and the mask main body 1.
Further, similarly to the example of FIG. 8 described later, a cooling sensation agent sheet (see reference numeral 35F) having the same size as the sticking part 32 is interposed between the sticking parts 32 and 32 and the mask main body part 1. The cooling sensation sheet (see reference numeral 35G) may be disposed on the outer surface of the elastic member 31 as in the example of FIG.

  In the case of a mask in which the above-mentioned cooling sensation agent is arranged, vasoconstriction is achieved by the cooling sensation agent, and it becomes possible to perform better nasal breathing by synergistic effect with improvement of nasal congestion and expansion of the nasal cavity. The occurrence of fogging can be further reduced.

[Fifth embodiment]
Another example of the mask is shown as the fifth embodiment. FIG. 8 illustrates a mask in which a fragrance is arranged on the nasal cavity expansion portion 3F.
Nasal congestion caused by autonomic nerve disturbance may be improved by a relaxation effect due to suction of the fragrance. Therefore, it is expected that an fragrance is included in the mask, the nasal congestion of the mask wearer is improved, and the nasal breathing is performed well.
Examples of the fragrances include aroma oils (essential oils), and eucalyptus, lavender, myrtle and tea tree are particularly effective.

The fragrance is desirably disposed inside the mask main body 1 in order to perform suction well and reduce the influence on the surroundings. For example, as shown in FIG. 8, a fragrance sheet 35 </ b> F containing a fragrance having the same size as that of the sticking part 32 is inserted between each sticking part 32, 32 and the mask body part 1. Also good.
Although the suction effect is inferior, as in the example of FIG. 7 described above, a fragrance sheet (see reference numeral 35E) having the same size as the elastic member 31 is placed between the elastic member 31 and the mask body 1. It may be inserted, or a fragrance sheet (see reference numeral 35G) may be arranged on the outer surface of the elastic member 31 as in the example of FIG.
In addition, a fragrance | flavor may be included in the mask main-body part 1 between the elastic member 31 and each sticking part 32 and 32, the elastic member 31 is formed from a porous material, and an aromatic is directly attached to the elastic member 31. An agent may be included.

In addition, a fragrance | flavor sheet | seat may be provided in a mask with the cooling sensation agent sheet mentioned above or the warm sensation agent sheet | seat mentioned later, and nasal congestion may be improved with each effect.

[Sixth embodiment]
Another example of the mask is shown as the sixth embodiment. FIG. 9 illustrates a mask in which a warming agent having a warming effect is disposed on the nasal cavity expanding portion 3G.
It is known that nasal congestion is improved by dilating blood vessels and adjusting autonomic nerves. Therefore, the mask is given a warming effect by the warming agent, the nasal congestion of the mask wearer is improved, and the nasal breathing can be performed well.
As the warming agent, there are a single component having warming effect and a warming effect by reaction with moisture. Examples of the former include capsaicin, nonylic acid vanillylamide, and examples of the latter include iron powder and calcium oxide.

Some of the above-mentioned warming sensates have some effects such as irritation on the skin, so it is desirable to arrange them so as not to touch the skin directly. For example, as shown in FIG. 9, a warming sensation sheet 35 </ b> G containing a warming sensation of the same size as the elastic member 31 may be disposed on the outer surface of the elastic member 31.
Further, similarly to the example of FIG. 7 described above, a warming agent sheet (see reference numeral 35E) having the same size as the elastic member 31 may be interposed between the elastic member 31 and the mask body 1. As in the example of FIG. 8 described above, a warming sensation sheet (see reference numeral 35F) having the same size as the sticking part 32 is interposed between the sticking parts 32 and 32 and the mask main body part 1. It may be inserted.

  In the case of the mask with the above-mentioned warming sensation, the vasodilation and adjustment of autonomic nerves are achieved by the warming sensation, and it is possible to perform better nasal breathing by synergistic effects with nasal congestion and improvement of nasal congestion Thus, the occurrence of fogging of glasses or the like can be further reduced.

[Seventh embodiment]
The example of a mask provided with the nasal cavity expansion part 3H which changed arrangement | positioning of the elastic member 31 as 7th embodiment is shown. FIG. 10 is a cross-sectional view of the nasal cavity extension 3H.
Since the elastic member 31 has a foreign object sensation when directly touching the skin, it is desirable that the elastic member 31 is arranged so that the elastic member 31 does not touch the skin directly with the sheet material of the mask main body 1 interposed. However, the arrangement for realizing this is not limited to the case where the elastic member 31 is arranged on the outer side surface of the mask main body 1, and can be arranged on the inner side surface.
That is, as shown in FIG. 10, the elastic member 31 is fixed in the vicinity of the upper end portion of the inner side surface (the rear side surface in the drawing) of the mask main body portion 1, and the upper end portion of the sheet material forming the mask main body portion 1 is elasticated. The member 31 is folded back so as to wrap, and the end portion of the folded sheet material is fixed to the inner surface of the sheet material below the elastic member 31.
Further, on the inner side surface of the folded sheet material, sticking portions 32 and 32 are provided at positions corresponding to the elastic member 31 and covered with release paper 33 and 33.
